River Island Channel & Floodplain Restoration

Metro, a regional government body, contracted Inter-Fluve to restore an abandoned gravel mine on the Clackamas River. In 1996 a 100-year rain-on-snow flood event caused the mainstem Clackamas River to breach a levee and flow through this active gravel mining operation. Goals of the project included: to strategically implement restoration actions in areas where existing processes are insufficient to create or maintain highly functioning habitats, restoring perennially hydrologic connectivity to tributary habitats, and supporting multiple values including salmonids, stillwater species, and wildlife habitat, riparian and floodplain forests, water quality and recreation.

Dam Removals

From California to Maine, dams across the United States are being removed to help fish, improve safety and boost recreation. We’ve worked on over 100 dam removals and performed construction oversight on over 35.


Estuary Restoration

Estuaries are dynamic ecosystems where oceans, rivers and human economies converge; they’re also critical to rearing grounds for fish and wildlife. Across the country, we’re reconnecting and restoring these habitats.


Wetlands & Peat Bogs

Holistic ecological restoration of cranberry bogs to native stream and wetland ecosystems was pioneered by Inter-Fluve. Today, we’re applying lessons learned to cranberry farms throughout New England.
